Session Abstract

North-West Europe (NWE) has to reduce CO2 emissions. One major source for the latter is the production of electricity and heat by burning fossil fuels. Replacing this process through the implementation of deep geothermal energy (DGE) could significantly aid to the reduction of CO2 emissions and hence support a sustainable energy generation. However, the exploration of hydrothermal DGE targets in most NWE regions requires comprehensive investigation and specific geologic and engineering expertise considering the generally complex setting including strongly faulted and folded horizons of highly permeable carbonate rocks, in the border area consisting of Germany, France, the Netherlands and Belgium.

It is the objective of DGE-ROLLOUT to promote the use of DGE and also to reduce CO2 emissions through the initiation and optimization of particular pilot projects. This is aimed to be achieved using a multi-disciplinary approach including the improvement of the current insufficient data situation, the compilation and development of innovative decision and exploration strategies, as well as the optimization of existing DGE manifestations. Therefore, the DGE-ROLLOUT project comprises three work packages: Mapping and networking (WP T1), Decision and exploration support (WP T2) and Testing for production optimization (WP T3).

WP T1 seeks to provide a reconciled and common knowledge baseline for the DGE market development in the project area, including the preparation of a transnationally harmonised depth and thickness map of the currently targeted Lower Carboniferous carbonate reservoir rocks. WP T2 intends to fill existing information gaps by acquiring transnational 2D seismic surveys, conducting drilling operations, reprocessing vintage 2D seismic data, and producing a variety of subsurface 2D and 3D models. WP T3 aims to increase the efficiency of existing geothermal systems, and to implement new or improved production techniques in the fields of reservoir behaviour, cascading systems and thermal energy storage.

Besides the Geological Survey of North Rhine-Westphalia as the lead partner, the DGE-ROLLOUT project partners include the national geological surveys of Belgium, France and the Netherlands, as well as industry partners (DMT GmbH & Co. KG; Energie Beheer Nederland B.V.; RWE Power AG) and research institutions (Fraunhofer Institution for Energy Infrastructures and Geothermal Systems; Technical University Darmstadt; Flemish Institute for Technological Research).

Our Side Event in the course of the European Geothermal Congress 2022 will provide an overview of the work that has been undertaken throughout the DGE-ROLLOUT project’s lifetime (Oct 2018 – Oct 2023), present major results that have been achieved, and give an outline of the approach to foster the development of DGE for both small- and large-scale infrastructures. Our Side Event will be subdivided into four thematic blocks comprising 1) Mapping the DGE Potential of North-West Europe, 2) Supporting DGE Exploration, 3) DGE Case Studies and 4) Upscaling DGE for Industry.
